Title: 반도체 메모리회로
IPC: G11C7/10
Filed: 1998-10-26
Abstract: 데이터 판독선이 비선택상태에 있을 때,  데이터 선택선은 "L"레벨에 있으므로,  NMOS 트랜지스터는 온(on)으로 되고,  데이터 판독선에 콘덴서의 용량이 부가된다.     그러므로,  데이터 선택선이 "H"레벨로 된 직후 커플링 용량의 영향에 기인하여 데이터 판독선의 전위상승은 작다.     그 후에,  메모리셀 데이터는 데이터 판독선에 전달되지만,  이 때,  NMOS 트랜지스터는 오프상태로 되므로,  데이터 판독선의 용량은 줄어들어,  데이터의 판독속도는 영향을 받지 않는다.     결과적으로,  커플링 용량에 기인한 신호간섭은 줄어들 수 있다.

Title: Bonding circuit of option pad for semiconductor memory device
Inventor: KIM DAE YONG
IPC: G11C5/14
Filed: 1998-12-15
Abstract: PURPOSE: A bonding circuit of option pad for a semiconductor memory device is provided to convert a level of source voltage fed from an outside to a level of internal source voltage when the source voltage fed from the outside is higher than the level of internal source voltage. CONSTITUTION: A voltage subtracted threshold voltages of PMOS transistors(P1,P2) from a source voltage(VCC) is hung in a node(A) when the source voltage is fed in a source voltage pad. The voltage within 3V-7V is hung in the node(A) when the voltage within 4V-8V is fed. A voltage fed to a gate of NMOS transistor(N7) is a higher voltage as the threshold voltage or a voltage between a base and an emitter of bipolar transistor than the level of internal source voltage. The reason to feed the higher voltage than the level of internal source voltage is that the internal source voltage is fed to a source of PMOS transistor to compose an inverter(I1). The voltage of node(A) is transmitted to a node(B) as it is when the voltage hung in a drain of NMOS transistor(N7), that is the voltage of node(A), is smaller than a threshold voltage of NMOS transistor(N7) in a control voltage. And the voltage subtracted the threshold voltage of NMOS transistor(N7) from the control voltage is transmitted to the node(B) when the voltage of node(A) is larger.

Filed: 1997-04-15
Abstract: PURPOSE: A transgenic plant containing DNA encoding AC1/C1 wild type and mutant sequences that negatively interfere in trans with geminiviral replication during infection is provided which is resistant to viral infection. CONSTITUTION: In the transgenic plant containing DNA encoding AC1 mutants, levels of AC1 expression directly relate to levels of trans-dominance and replication as shown in Fig. 1. According to the figure, replication is observed in inoculations with wild type BGMV-DNA-A plus carrier DNA(A+PBS). No replication is observed in inoculations with a mutant of DNA-A containing double mutations coinoculated with carrier DNA(ADM+PBS). Replication of double mutations is, however, complemented by trans expression of wild type AC1 in transient expression vector(ADM+TAC1). Replication of BGMV-DNA-A in the presence of two different AC1 mutants, treatments A+TDM and A+TD¬262R reduced replication of virus DNA-A compared to the A+PBS treatments. Accordingly, trans expression of AC1 mutants can inhibit replication of BGMV-DNA-A.
